WINDOW.

SPECIFICATION forming part of Letters Patent No. 447,362, dated March 3, 1891.

v Application filed September 4,1889. u Serial No. 322,939. (No modal.)

To all whom it may concern.-

State of Pennsylvania, have invented certain new and useful Improvements in Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates toan improvementin windows, and more especially to an improve- February 19, 1889, to Benjamin F. Dettra and myself jointly, constitutes one.

l-litherto in this class of inventions it was considered necessary to locate the weight-cord pulleys at the extreme top of the windowframes in order to allow for the tilting of the sash from the highest point possible. Also in the patent above referred to there were one or two other features which, while they performed the functions admirablyfor which they were originally intended, yet in the course of actual tests it has been found by slight modiiications in some of the parts that still better results could be attained, thus greatly enhancing the value of the windows without adding in the slightest degree to the complexity of parts or of the market value of the windows. It is the object of my present invention to provide these additional features and to obviate all objectionable features found in this style of windows.

To this end my invention consists in a device by the use of which it is unnecessary to change the location of the Weight-cord pulleys from their usual position to a position nearer the top of the frame.

It further consists in an improved fastener,

whereby the care in placing the bolt exactlyl in the middle of the side rail is rendered unnecessary, and the danger of accidental displacement of parts in the course of the different adjustments of the sash is avoided.

It still further consists in certain novel features of constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a Window frame and sashes with improvements attached. Fig. 2 is a detached View of the fastening device.

Fig. 3 is a sectional View of the same on the line :t x of Fig. 2. Fig. 4L is asimilar view on the line y fy of Fig. 2. Fig. 5 is a detached vieur of the weight-cord attachment or clamp. Fig. 6 is a sectional view of the same, and Fig. 7 is a transverse sectional view with the window-sashes partly open or at right angles to each other.

A represents a Window-frame having the usual stiles 1 1 on its vertical sides and the central bead 2 parallel with the stiles, and between which and the latter the uppersash e and the lower sash A are guided.

B is a cord-holding attachment or clamp, preferably made of cast metal of a Width to loosely fit the grooves formed between the stiles and center bead and sufficiently long to insure against displacement or binding in the groove and to reach from the weight-pulley to the top of the frame. To make the attachment as light as possible, it is hollowed out in the back and slotted through the cen` ter; but a sufficient portion is left at the ends to form bearings 5 5, which travel in the window-frame grooves. A flattened depression 6 is formed in one end of the attach-v ment and in its center a recess '7 is made, across which two or moreA lugs 8 8 extend. A removable clamp-plate 9 is furnished with a groove or recess 10, which corresponds with the recess 7 and is adapted to lie over it to form a round or cylindrical socket 1l. This recess is adapted to receive p the end of the weight-cord, and a lug l2 on this plate extends between the two lugs 8 8. Byscrewing this plate down tight into the depression the end of the cord is given a zigzag' bend between the three lugs 8, 12, and 8, whereit is securely held as long as the plate isscrewed down. -When thus fastened, the outer face of the plate extends flush with the face of the body of the attachment, and said faces extend flush also with the edge of the central bead 2 of the frame. This is necessary because the sashes swing out laterally and must meet with no obstruction. A shank 14 is mortised in the edge of the upper sash and fastened thcrein,`and the extreme upper end IOO of this plate and the corresponding end of the attachment are pivoted together. The weight-cord extends up through the hollow or recessed back of the attachment and thence over the pulley, which maybe at the extreme top of the frame or the usual distance therefrom, it being simply requisite that this attachment B should be long enough to span the space between the pulley and the upper end of the sash, as it is the primary object of this invention to so arrange the parts that this pivotal support may he shifted to any point between the eXtreme top of the frame and a point as near to the lower end of the frame as the exigency ever requires.

A pair of duplicate sash fasteners and connectors 17 17 are placed on the meeting-rails of the two sashes 3 and et. The fasteners each have a slide-bolt 1S, each of which is fitted in a holder 19 and extends through the outer side rail of the upper sash. There is an inverted-T-shaped slot in the side of each of these holders at or near the middle, through which an arm 20, projecting from each bolt, extends. These arms are adapted to turn into the upper restricted portion of the slots when the sashes are to be raised or lowered after the usual fashion, the outer ends of the bolts still projecting into the grooves in the window-frames far enough to guide them and prevent their being swung out laterally. By moving the arms in the enlarged ends of the slots the bolts are withdrawn from their grooves, allowing lateral adjustment of the sashes, or on the other hand the sashes are fastened together and made burglar-proof. A small spring 2l in each frame bears on the bolt and arm to retain them in any position. The plates with which the free ends of these arms 2O engage are located on the meeting-rail of the other sash just opposite the holders 19. Upwardly-projecting L-shaped lugs 22 on these plates receLve the arms beneath them when the bolts are pushed outward, thus forming a rigid lock for both sashes, preventing them from being raised or lowered, while the outer ends of the bolts, by' extending into the grooves between the central bead and the stiles, prevent the upper sash from being pushed or pulled out, and this sash always controls the other by overlapping at the meeting-rails.

Perforated lugs 2l 2st project upwardly from the plates on sash 4 opposite lugs 22, and these lugs are each furnished with a perforation 25, adapted to receive the pintle ends of the arms 2O when the windows are to be moved out laterally to form a hinge, thus forming a loose joint or connection between the two sashes, and to absolutely prevent these pintles from slipping out of their sockets or the perforations 25 when the sashes are tilted. A rounded narrow projection 26 is formed on the free end of each arm, which enters a recess 27, formed for it in the plate as soon as the sashes are at an angle to each other. This prevents any slipping of the pintle and constitutes one of the features of improvement in the present invention.

In the patent herein referred to a head was mounted at its center on the ou ter end of each locking-bolt, and these heads entered the grooves in the sash-frame to guide the sashes and act as anti-friction pulleys therein. Considerable difficulty was frequently encountered in centering the heads so as to exactly enter the grooves, and unless the holes in the side rail of the upper sash were precisely in the right place the head would hit the Stiles or bead. To obviate this, a centering device consisting of a small plate 30 is pivoted at its center to the head 3l, and this plate is pivoted at one end on the outer end of the bolt. A pin S2 projects inward from the opposite end of the plate. After the bolt is inserted through the side rail of the sash the head is pnt on the bolt and turned around on it until properly centered in the frame. A hole is then made in the sash to receive the pin at the point where it falls, and the pin is inserted in this hole. The end of the bolt may then be upset in the plate through the hole 33 in the head, if desired, to retain it in place and prevent its removal.

It is evident that slight changes `might be' resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the particular construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.` The combination, with a window-frame, of sashes mounted therein capable of sliding past each other or being laterally tilted, and a hinge connection between the sashes, said hinge being capable of disconnection when the meeting-rails of the sashes are together, but incapable of disconnection when the sashes are tilted, substantially as set forth.
